Well, I don't know. You could argue that NOS done right IS new technology. I mean, nobody was building DACs like this 15 years ago! Just because upsampling came later than the original (default) NOS route doesn't mean it's superior.
Have you heard one of these newer-breed NOS/filterless DACs? I'm telling you, it sounds like analog. I sounds like vinyl. I am not kidding. No, not just as good as the best vinyl, of course, but really good, and analog in a very similar way to good SACD!
I too find it ironic that the path to "vinyl goodness" can be had both by tons of information (DSD) and good 'ole 16bit/44Khz with a really simple DAC.
